• Filtering waste from the blood

Open Ended

Why is understanding the nervous system important for studying human anatomy and physiology?

Multiple Choice

Which components make up the nervous system, and what is its primary function in the body?

• Brain, spinal column, and nerves; master controlling and communicating system

• Heart, lungs, and blood vessels; circulatory system

• Bones, muscles, and joints; support and movement

• Stomach, intestines, and liver; digestion

Fill in the Blank

Fill in the blank: The central nervous system consists of the brain and ___.

Multiple Select

Which of the following statements about afferent and efferent neurons are correct?

• Afferent neurons carry impulses toward the CNS.

• Efferent neurons carry impulses away from the CNS.

• Somatic afferent fibers transmit impulses from visceral organs to the brain.

• Efferent neurons cause movement by transmitting impulses to muscles and glands.

Multiple Choice

Which part of the nervous system is responsible for subconscious control of smooth muscle, cardiac muscle, and glands?

• Somatic nervous system

• Autonomic nervous system

• Central nervous system

• Peripheral nervous system

Open Ended

Compare and contrast the somatic nervous system and the autonomic nervous system in terms of control and function.

Multiple Choice

Which division of the nervous system is responsible for the 'fight or flight' response and what are some of its effects on the body?

• Sympathetic nervous system; increases heart rate and dilates pupils

• Parasympathetic nervous system; promotes digestion

• Central nervous system; controls reflexes

• Somatic nervous system; controls voluntary muscles

Multiple Choice

Which of the following statements about the parasympathetic nervous system is correct?

• It is most active during stress and danger.

• It is known as the 'resting and digesting system.'

• It increases heart rate and dilates pupils.

• It is responsible for voluntary muscle movement.

Fill in the Blank

Fill in the blank: The two main divisions of the autonomic nervous system are the sympathetic division and the ___ division.

Multiple Select

Which of the following are effector organs of the autonomic nervous system?

• Smooth muscle

• Glands

• Cardiac muscle

• Skeletal muscle

Open Ended

What are the two principal cell types of the nervous system, and what are their main functions?

Multiple Choice

Which supporting cell in the CNS is responsible for monitoring the health of neurons?

• Microglia

• Ependymal cells

• Oligodendrocytes

• Schwann cells

Fill in the Blank

Oligodendrocytes produce fatty insulating coverings called ___ sheaths.

Multiple Choice

Which of the following is NOT a characteristic of neuroglia in the PNS?

• Able to transmit nerve impulses

• Resemble neurons structurally

• Never lose their ability to divide

• Include Schwann and satellite cells

Open Ended

Explain the differences between Schwann cells and satellite cells in the peripheral nervous system (PNS).

Multiple Select

Which of the following are functions of the myelin sheath?

• Protect the axon

• Increase the speed of nerve impulse transmission

• Monitor the health of neurons

• Electrically insulate fibers from one another

Open Ended

Describe the structure and main functions of a neuron.

Multiple Choice

Which of the following best describes the two main types of neuron processes?

• Axons and dendrites

• Nucleus and axon hillock

• Schwann cells and nodes of Ranvier

• Nissl bodies and nucleolus

Multiple Choice

What is the primary function of dendrites in motor neurons?

• Receive incoming messages and convey them toward the cell body

• Transmit impulses away from the cell body

• Store neurotransmitters

• Provide metabolic support for the neuron

Multiple Select

Which of the following statements about axons of motor neurons are correct?

• They usually have only one unbranched axon per neuron

• Axon terminals contain vesicles with neurotransmitters

• They are the receptive regions of the neuron

• They arise from the axon hillock

Open Ended

• Sensory (afferent) neuron

• Motor (efferent) neuron

• Association neuron

• Effector neuron
